CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 416,029, dated November 26, 1889. Application filed July 8, 1889. Serial No. 816,751. (No model.)

T0 at whom it may concern.-

Beit known that I, ISRAEL DONALD BOYER, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash Registers and Indicators, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings, in which- Figure 1 represents a side elevation of a portion of a well-known form of cash-register having my improvement applied thereto and having the rear side of the case or cabinet removed and a portion of the frame -work broken away and some-of the Operating parts on the opposite side of the machine removed. Fig. 2 is a sectional side elevation of the lower and rear side of the machine, and showing the parts not illustrated in Fig. 1. Fig. 3 is a rear elevation of a portion of the machine. Fig. t is a detail of the locking-bar and the Fig. 5 is a detail of the arresting devices for the vibrating bar. Fig. 6 is a detail of the wiper-block and trigping-dog for actuating the wing.

The same letters of reference are used to indicate identical parts in all the figures.

The frame-work A, which supports the working parts of the machine, is inclosed in the usual case or cabinet B, having in its lower portion a drawer-compartment, in which is fitted a money-drawer or till C.

D are the, operating-keys pivoted on the shaft E, their front ends projecting through slots in the front of the case B, and provided with numbered finger-buttons, while on their rear ends rest the usual tablet-rods F, carrying numbered indicating-tabletsat their upper ends and provided with shoulders at, which are engaged by the supporting-wing G to hold up an elevated tablet-rod in the usual manner. The wing G has atone side an upward extension H, which carries the gong- J of the vibrating bar or frame K which extends across all the keys and is moved by the operation of any one of them to actuate the win gpl 'and gong-hammer through the medium of the bell-crank I and tripping-dog c in the usual well-known manner. A flat spring j, bearing on the extension II at one endof the wing, and at the other end a coiled spring g, connected to an upwardly-extending arm h, secured to the wing and to a fixed point of the frame-work, serve to yieldingly hold the wing G, extension H, and gong-hammer in their normal positions. Pivoted to and depending from a lug 1', extending rearwardly from the wing G, is a link L, the lower end of which is pivoted to the outer end of the lever M, which is pivoted to a support at j, Fig. 3, and carries at its inner end the locking-bolt N, which, when the drawer is closed, engages the slotted locking-plate O, secured to the upper rear side of the drawer, and holds the latter in its closed position. \Vhen a key is Operated and the wing G pressed backward through the mechanism before described, the link L and outer end of the lever M are de- 7 5 pressed, the inner end of the lever M lifted, and the bolt N freed from the locking-plate O, whereupon the drawer is propelled from its compartment by the spring P.

The registering mechanism may be of any suitable character; but in the machine illustrated in the drawings it is of one of the usual well-known forms employed In such machines, consisting of two banks of individual registering-wheels (shown in dotted lines in Fig.1) carried on longitudinal shafts supported in a supplemental frame Q, the squared ends R R of which shafts are shown in Fig. 1. The wheels of the lower bank are actuated by the weighted dogs is, pivoted to 0 the keys D, and the wheels of the upper bank are actuated by and register the revolutions of those of the lower bank in the well-known manner,

Heretofore in this class of machines the vibrating bar K has been hung by its side arms J on the pivotal shaft E of the operating-keys, and its principal function was to furnish a common actuator for the supporting-wing and the gong-sounding and drawerroo lockin g mechanisms. In my present improve ment I give this bar additional functions to perform,the first of which arises from so constructing and arranging it and combining it with the operating-keys as to constitute it a key-coupler which locks together all keys which are displaced from their normal position at substantially the same time and compels uniform movement in their further operation. For this purpose I hang the bar K by its arms J on a shaft S, located above and in rear of the pivotal point of the keys, and provide the lower rear edge of the bar K with a rearwardly-extending flange 1, extending its entire length and resting on the upper sides of the keys. The upper side of each key, just in rear of the flange Z of the bar K, is provided with a slotted lug, which forms a hook m, whose open mouth is in close proximity to the rear edge of the flange Z. It results from this construction and the pivotal arrangement of the bar K above the keys D that when a key is operated the flange Z will enter the mouth of the hook m, and the key be thereby locked to the bar K, as shown by the dotted lines at l in Fig. 1. If two or more keys'are started at the same time, they will all become locked to the bar K in the same manner, and if any key-button is released by the operator its key will be carried on down and the registration of its value effected by the depression of the other key or keys which were started with it.

Another feature of my invention consists in combining a key-arrester with a movable bar, which extends across a series of keys and is moved by the operation of any one of them, and, further, in combining such bar and arrester with a series of keys which are so constructed that each of them becomes locked to said bar when partially operated, for it will be evident that if the keys are locked to said bar from the time they are displaced from their normal position until they are returned to such position, and a key-arrester be applied to said bar in such manner that the bar is arrested and held atany point where the key is released before full operation and cannot be reset until thekeyis fully operated, a single key-arrester so combined with such bar will act as a common arrester for all the keys and prevent the resetting of any one of them, when partially operated, until it has been operated to its full extent. As one form of such arrester, and as a suitable method of combining it with such bar, I have secured to one of the side arms J of the bar K a notched plate or rack T, having downwardly-presentin g teeth. Pivoted to the frame A at a point above this rack is a bell-crank U, whose lower vertical arm m is provided with a shoulder 0, which, owing to the weight of the horizontal arm 19 of the bell-crank and the pivotal arrangement of the latter, normally bears against the rack T, and when the latter is lifted by the operation of a key and the lifting of the bar K slips over and acts as a pawl for engagement with the teeth of the rack, so that if the key and bar be released at any point in their upward travel the shoulder 0 will engage a tooth of the rack T and hold the bar K and the key which is locked to it at exactly the point where they were released. Projecting laterally from the side arm J in rear of the rack T is a pin g, which, as the key and bar K reach their full limit of upward motion, strikes the under side of and lifts the horizontal arm 1) of the bellcrank U, as shown by the dotted lines at 2, Fig. 1, and throws the vertical arm 02 away from the rack T, thereby disengaging the shoulder 0 from the teeth of the rack.

V is a weighted latch for holding the arm n and shoulder o away from the rack until the key and bar K are reset. It is pivoted at r to the frame-work A, and its upper rear end 8 has a lateral projection or is made of such width as to extend beneath and bear upward against the under side of the arm J, as shown in Fig. 5, being normally held in such position by the gravity of its enlarged and weighted opposite end. When a key is operated and the bar K and arm J lifted, the forward weigh ted end of the latch drops upon the stop-pin z, causing the latch to assume the position shown by the dotted lines in Fig. 1. As the operation of the key continues and the arm J is lifted and the pin 1 strikes the under side of the arm p of the bell-crank U and throws its arm n away from the rack T, the lower end of the arm n flips over the upper rear end 8 of the latch V and is held by it in the position shown by the dotted lines in Fig. 1 until, as the operated key and the bar K and arm J return to their normal position, the under side of the arm J strikes the upper rear end 3 of the latch V and moves the latter back to the position shown by the solid lines in Fig. 1, thereby releasing the arm n, which then falls by gravity against the rack T, ready for a fresh operation. It results from this construction and arrangement that whenever any key is substantially displaced from its normal position it cannot be returned to such position until ithas been operated to its full extent and its total value registered. This feature of my invention, therefore, while useful in a machine provided with a series of individual registering-W11eelsone for each key and each turned one number by the operation of its key, as above describedis perhaps more valuable in a machine provided with a registering-wheel common to and actuated to different degrees by a series of keys of different values, for in such machine it is absolutely essential to accurate registration that each key operated be actuated to its full extent. So far as this feature of my invention is concerned I do not wish to be limited either to the particular form of arresting devices applied to the vibrating bar or to the particular manner of locking the keys to said bar, it being sufficient for the purposes of the invention that there be a movable bar common to and moved by each of a number of keys, each of which keys becomes locked to said bar when operated, andan arrester which engages the bar and prevents it being reset until the operated key has been actuated to its full extent.

The combination of the arresting devices with the movable bar extending across the keys forms a novel and valuable feature of my invention independently of the locking of athe keys to said bar, and may be advantageously employed in machines where the keys are not arranged to be locked to the bar -an instance which will be hereinafter pointed out in connection with the descriptionof other features of my invention. The next-feature of my invention consists in combining with a movable bar common to and moved by each of a number of keys and an arrester for such bar a locking-bar actuated by said movable bar when any key is operated to lock the unoperated keys from operation. Any usual or suitablelockingbar may be used in this combination; but I have devised one of novel form and operating in a novel manner, and which of itself constitutes a novel feature of my invention aside from its combination with the movable bar and arrester. This novel locking-bar (lettered WV in the drawings and shown in cross-section in Fig. 2) extends across the rear of the machine slightly in rear of and a little above the ends of the operating-keys D, and is pivoted at its ends in the sides of the frame-work A or other suitable supports, so as to oscillate freely in its bearings. It may be a flat bar of any suitable shape in crosssectionsu ch as oval-or, as illustrated in the drawings, it may be substantially semi-cylindrical in form, having its side next the ends of the keys cut away or flattened. Rigidly secured to this bar at one end is an arm X, (in this instance by a collar Y and set-screw 1a,) the forward end of which arm is connected to an extension of one of the side'arms J of the vibrating bar K by slot-and-pin connection at n. It results from this construction and arrangement of the parts that when a key is operated and the bar K and arm J lifted the forward end of the arm X will be lifted with the arm J and the locking-bar WV be rocked 'to the position shown in Fig. 1, thereby moving over the ends of the unoperated keys and locking them from operation. The bar W is so shaped and arranged in such proximity to the ends of the keys that a slight oscillation of it by the partial opera tion of any key is sufficient to cause it to move over the ends of and lock the unoperated keys, and,inasmuch as the bar K is arrested and held at any point less than full operation by the arrester before described and cannot be reset until actuated to its full extent, it results that after any key has been substantially displaced from its normal position the bar W moves over the ends of all the unoperated keys and beneath the end of the partially-operated key, so that the latter cannot be reset nor any of the other keys operated until the partially-operated key is further operated andits full value registered. The partially-operated key could not be reset before full operation for the further reason that it is locked to the flange of the bar K by its hook on and must move with said bar; but this locking of the keys to the bar K is independent of the operations of the bar W, and if the keys were of the ordinary construction, provided with no hooks and free to move up and down independently of the bar K, the result above described would be the same, for the partially-operated key when released would fall until its rear end rested on the'uptu'rned fiat side of .the bar WV, but could go no farther. So far as this feature of the invention is concerned, therefore, the bar W operates both as a keylocking and key-arresting bar.

Another feature of my invention relates to novel means for preventing the operation of the keys while the money-drawer is open. It may be employed either in connection with or independently of the other features of the invention above described, although in the present case I have shown all my improvements associated together and applied to one machine. Loosely pivoted to one of the side arms J of the bar K is a pendent latch-arm Z, which is normally held in the position shown by the solid lines in Fig. l by a lateral projection 10, Fig. 5, on the upper end of the vertical arm 00 of a bell-crank A, pivoted to the frame-work of the machine, as shown in Fig.1, and whose other arm y is connected to the horizontal arni z of a second bell-crank B, loosely pivoted to any suitable supportin this instance hung on the bearing end of the locking-bar W-and whose vertical pend-- ent arm ct extends down into the drawercompartment and carries an adjusting-screw b. When the drawer G is closed, its upper rear end bears against theforward end of the screw b and holds the two bell-cranks and the arm Z in the position shown by the solid lines in Fig. 1. lVhen a key is operated and the drawer released and partially propelled from its compartment, a coiled spring 0' pulls the two bell-cranks into the position shown by the dottedlines in Fig. l, whereupon the arm Z falls against the side of a bracket lug d, projecting inwardly from the frame-work A, and as the key and the arm J and bar K reach their limit of motion the lower end of the arm Z moves over and rests upon the base of the lug d and thereby latches the arm J and bar K in the position shown by the dotted lines in Fig. 1. In this position of the parts the locking-bar V is in the position shown in Fig'. 4, all the unoperated keys are locked by it, and the operated key cannot be rese'gboth because it is locked to the bar K, as shown at l in Fig. 1, and because if it were not locked to the bar K the bar V would prevent its resn ming its normal position. hen

the drawer O is again pushed in, its rear end strikes the screw 1), carried by the pendent arm a of the bell-crank B, and throws the two bell-cranks back to the position shown by the solid lines in Fig. 1, thereby causing the lateral projection on the upper end of the arm a; of the bell-crank A to knock the lower end of the latch-arm Z off the bracketlug d, whereupon all the parts are free to resume their normal positions of rest. (Shown by the solid lines of Fig. 1.) Fonthe purpose of throwing out of operation this mechanism actuated by the opening and closing of the drawer, so that the machine can, when desired, be operated with the drawer either open or closed, I provide a lever O, pivoted to the frame-work at c, and whose lower end extends over and rests against the lug (1 when the lever is in the position shown by the solid lines in Fig. 1; but when its handle f is pulled forward until the spring-detent g takes into the notch h the lower end of the lever is thrown backward, so that when the drawer is opened the projection '10 on the upper end of the arm 00 of the bellcrank A strikes against and is arrested by the lower end of the lever C and holds the arm Z away from the lug ct, so that said arm moves freely up and down with the movements of the bar K, but its lower end cannot move over and be caught upon the lug d Having thus fully described my invention, I claim' 1.
